Fan L44556-001

NOTE: To properly ventilate the computer, allow at least 7.6 cm (3.0 in) of clearance on the sides of the

computer. The computer uses an electric fan for ventilation. The fan is controlled by a temperature sensor and

is designed to turn on automatically when high temperature conditions exist. These conditions are aected by

high external temperatures, system power consumption, power management/battery conservation

congurations, battery fast charging, and software requirements. Exhaust air is displaced through the

ventilation grill.

Before removing the fan, follow these steps:

1. Prepare the computer for disassembly (Preparation for disassembly on page 29).

2. Place the computer in Battery Safe mode (Battery Safe mode on page 29).

3. Remove the bottom cover (Bottom cover on page 30).

4. Remove the battery (Battery on page 31).

3. Lift the tape that secures the fan to the heat sink (3).

4. Rotate the left side of the fan upward (4), and then lift the fan from the computer (5).
